Number of expansion joints needed for a specific length of pipeline

Hello Andrew,

I agree with Mike, that information you provided are very poor for engineering decision, so flexible joints selection and modelling is much more complex than it might seem to be. However, in the straight pipe on the rack, you may calculate total thermal expansion between ending bends and then compare this value with allowable longitudinal deflection of available expansion joints. This is a simplification of the process, because you may also use lateral expansion joints in branches AFTER of BEFORE bends. This is also a very effective method, sometimes inevitable. Axial expansion joints have some STRICT REQUIREMENTS that you need to follow in case of a pipeline.

Please, remember that 'real-life' expansion joint' in AutoPIPE need to be usually assembled from several elements - a lot of information you may find in Help.
